A method for simultaneous recovery of crude oil from multiple zones in a reservoir is disclosed wherein multiple wells, each in fluid communication with at least two hydrocarbon zones separated by an impermeable barrier, are used to produce oil in an enhanced recovery process. The end product from recovery in one zone is used to augment the recovery process in another zone.
A method for simultaneously recovering hydrocarbonaceous fluids from a formation or reservoir containing same having multiple permeability zones separated by a shaley layer comprising: (a) injecting via a first injection means provided in a well an oxygen containing fluid into a first hydrocarbonace
A method for simultaneously recovering hydrocarbonaceous fluids from a formation or reservoir containing same having multiple permeability zones separated by a shaley layer comprising: (a) injecting via a first injection means provided in a well an oxygen containing fluid into a first hydrocarbonaceous zone fluidly communicating with a first a production means provided in a well where said first zone is vertically diplaced from a second hydrocarbonaceous zone and separated by said shaley layer; (b) combusting in-situ said first zone and producing hydrocarbonaceous fluids containing carbon dioxide therein as a conbustion by-product from said production means provided in a well; (c) separating carbon dioxide from said hydrocarbonaceous fluids; (d) injecting carbon dioxide into said second zone via a second injection means provided in a well which is fluidly connected to a second production means provided in a well in said second zone while simultaneously producing fluids from said first zone; and (e) producing hydrocarbonaceous fluids containing carbon dioxide from said second zone via said second production means.
